The Minimax Game 

Minimax is a game for two players. Five digits are presented, one at 
a time, and used to create a three-digit and a two-digit number. 
Each presented digit can be placed in any available position, but 
once placed, it cannot be moved. 

Before any digits are presented, an operation (addition, subtraction, 
multiplication, or division) is chosen, and also a target (minimum or 
maximum). The aim for each player is to create the arrangement of 
three-digit and two-digit numbers, combined according to the 
chosen operation, which produces the better result according to the 
chosen target, minimum or maximum. 

For example, if addition and minimum are the chosen operation and 
target, and the five presented digits are 4, 6, 9, 2, and 5, the 
arrangement below of player AAA produces a better result than the 
arrangement of player BBB. 

Player AAA: 629 + 45 = 674 
Player BBB: 954 + 26 = 980 
(the lower value is 674, so AAA wins)

The Box Game 

Box is a game based on the relative positions of values along a 
number line. 

A player is presented with nine values, one at a time, each to be 
placed into one of nine positions. Only one value can occupy each 
position and once placed, a value cannot be moved. The position of 
each value must represent its relative size, between the overall 
highest and lowest values. If, when a value is presented, there is no 
position available to maintain the required order, then the value is 
discarded. 

The game can be played by two players. Each player completes an 
arrangement of the nine presented values. The player discarding 
the fewest values (and hence, placing the most values) wins. In the 
one-player game, the choices attributed to the second player are 
made automatically by the application. 

The game can be played using either integer values, decimal 
values, or negative values, according to the options selected. 



TI-73/ TI-83 Plus SMILE Mathematics App Page 13 



Starting the Box Game 

1 . From the SELECT A BOX GAME menu choose one of the 
following: 

1 :BOX (WHOLE NUMBERS) 
2:BOXD (DECIMAL NUMBERS) 
3:BOXN (NEGATIVE NUMBERS) 

2. Next the SELECT A BOX MODE menu defines a range for the nine 
values to be placed. For example, in 1:BOX (WHOLE 
NUMBERS) Choose either 1 :0 TO 1 00 or 2:0 TO 1 000. 

3. Then from the NUMBER OF PLAYERS screen choose: 

1:ONE PLAYER? 
2:TWO PLAYERS? 

4. From the INPUT PLAYER NAME screen, enter a three letter 
identifier for each player. 

Entering Player Names 

Press or to cycle the display through the available letters, in 
alphabetical order, and press H or [T] to move the cursor between 
the positions for each letter. When three letters have been chosen, 
press I enter | to confirm your choice. The game automatically 
launches.

Playing the Box Game 

The opening screen looks similar to the illustration below. 

BOX is the name of the second player. As this 
is a one-player game the part of the second 
player is taken automatically by the App. 



AAA is the name of 
the first player and the 
highlight indicates it is 
this player's turn. 

BIN shows the number 
of values discarded. 




54 is the number 
currently presented. 

First player AAA then 
player BOX must select 
one of these nine boxes 
as a location for 54. 



TO 100 is a reminder of the possible range 
of the nine presented values. 



Nine numbers are presented. Try to place the numbers in order 
with the highest at the top and the lowest at the bottom. The 
numbers are presented one at a time with the numbers still to come 
unseen until presented. The on-screen pointer is moved up or down 
the available locations by pressing and 0- Press I enter I to place 
the value in the location currently indicated by the pointer's position. 
If a value cannot be placed as required, press [del] to discard that 
value. 

A tally of the number of discarded values is shown under BIN on 
the screen.

Page 1 5 



If you select a location which would not maintain the order as 
required, a dialog box displays a message stating that the number 
does not fall between the minimum and maximum numbers. 
Pressing any key to acknowledge the message allows the game to 
continue. 



Player AAA has discarded 
1 value to this point. When 
the value 90 appeared, 82 -

The Matching Fractions Game 

The Matching Fractions game is based on the concept of 
equivalence between fractions. 

The aim of the Matching Fractions game is to identify the equivalent 
fractions within a displayed set of four fractions. The fractions can 
change to new values three times within each round. At the end of 
each round your performance is reported as a score based on the 
number of equivalent fractions successfully identified in each round. 
The game ends after a total of five rounds have been played. 

Example 

The fractions 2/4 and 3/6 are equivalent fractions because they 
both represent the same portions of a whole, which is one-half. The 
first diagram below shows a bar divided into four equal parts 
(quarters) with two of these parts shaded. 



The second diagram shows the same bar divided into six equal 
parts (sixths) this time with three of these parts shaded. 



TI-73 / TI-83 Plus SMILE Mathematics App 



Page 1 7 



The fractions 2/4 and 3/6 represent the same shaded portion of the 
whole bar. The fractions 4/8, 5/10, 10/20, and 50/100 also 
represent the same portion of a whole bar. There are an infinite 
number of fractions that also belong to this set. Within this set of 
possible fractions, all equivalent to each other, the fraction 1/2 is 
the simplest form for any of the fractions in this set. 

Viewing Help in Matching Fractions 

Text screens provide help with the procedure and game features. 
The screens advance when NEXT ( [graph I ) is pressed and the 
BACK ( [trace I ) option allows earlier text to be reread. 

The Help screens explain that: 

• There are two levels of challenge, and that level one is the 
easiest level. 

• At any time, the display shows four sets of fractions. 

• Press H or [TJ to highlight a displayed fraction, then press I enter I 
to activate the selection. 

• RESELECT produces new fraction values for all positions not 
already selected. After you press RESELECT three times to see 
four sets of fractions, the round ends. 



TI-73/ TI-83 Plus SMILE Mathematics App Page 18 



• There is an UNDO option which releases the first fraction chosen 
so that it can be repositioned, if desired. Undo is not available 
once a second fraction has been chosen. 

• END GO displays the score for that round. 

At the bottom of the final help screen, the DEMO ( |zoom| ) choice 
launches a demonstration game sequence with a text commentary. 
The demonstration pauses, to allow sufficient viewing time, and 
continues when NEXT is pressed. Press QUIT DEMO ([Y=]) on the 
last screen to move to the select an option menu. 

Starting the Matching Fractions Game 

1 . Select 2:MATCHING FRACTIONS from the SELECT AN OPTION 
screen. 

2. From the SELECT A LEVEL screen, choose LEVEL 1 or LEVEL 2, 
depending on the degree of challenge required.

The Angle Game 

The Angle game encourages the development of two important 
estimation skills. 

• Estimating the size of a given angle. 

• Creating an angle of a specified size. 

Angles are shown in multiples of 5°. Angles range from 5° to 90° or 
from 5° to 360°, depending on the option chosen. 

There are three activities within the Angle game: 

1 . Introduction — an interactive demonstration of how angles are 
drawn within the Angle game. 

2. Estimation — the player estimates the size of a given angle. 

3. Challenge — the player creates an angle of a specified size. 



TI-73 / TI-83 Plus SMILE Mathematics App Page 22

The Rhino Game 

Rhino is a puzzle game based on coordinates. At its simplest it 
reinforces the concept and use of coordinate notation to express 
position. After a little basic practice, the Rhino game becomes a 
strategy challenge. You have to discover the rhino's position using 
the minimum number of guesses. Information about the actual 
position of the rhino is displayed on screen after each turn. The 
challenge involves interpreting this information usefully.

Demonstration 

A rhino is at the corner of two New York streets. The objective of 
this game is to locate the position of the rhino. After two 
coordinates are entered, a helicopter pilot will report the distance of 
the rhino from that position. 

Tip This distance is measured in blocks. It is not a direct or diagonal distance, but 
the distance along the streets. 

In the demonstration, the coordinates 5 and 6 are entered. A 
distance of three blocks is reported and this information is also 
shown on the grid. The demonstration then marks, with an "x", all 
possible positions for the rhino, based on that information.

Playing the Rhino Game 

At the game's start screen: 

• Enter an x coordinate, then press \±\. 

• Enter a y coordinate, then press I enter I . 




The coordinates are entered in these two boxes. 



The result will show beside the coordinates. 
In this case, the rhino is two blocks away 
from position (5,6). 



Each result is also shown on the grid. 



The screen shows the coordinates that you chose and the number 
of blocks, which is the rhino's distance from that position. The 
number of blocks is also displayed on the grid, at the selected 
position.

Now enter another pair of coordinates and notice that the result for 
this position is displayed in the same way. Continue to enter pairs 
of coordinates until you find the rhino. The three most recent results 
are displayed on the right side of the screen. Press or to scroll 
through all the results, if needed. All results are also shown on the 
grid.

Press H or to scroll through all the results. 
The three most recent results are shown. 



If the result is a distance of 1 blocks or more, the actual number 
displays, then after any key is pressed, the number is replaced by a 
+ symbol. 



In this game the Rhino is 1 1 blocks away from 
the position (8,2). 

First the 1 1 shows on the grid, then when any 
key is pressed it is replaced by the + symbol.
